The "Mad Men" star borrowed gems from legendary jewelry company Chopard to wear to the star-studded event in Los Angeles.
But one of the matching diamond bangles slipped off her wrist as she made her way into the venue, and the actress turned to reporters for help locating the pricey piece, asking, "Have you seen a diamond bracelet? I've lost one that looks like this."
Hendricks reportedly left the auditorium as the other guests were taking their seats to continue her search for the bracelet, which was eventually handed back to her by an event worker who found the item.
A representative for Chopard confirms a relieved Hendricks was able to return all of the pieces she borrowed, telling the New York Post's gossip column Page Six, "Whoever put it on her wrist may have not closed the safety clasp correctly. But both bracelets and her earrings were returned in perfect condition today."
